The spectrum are the wavelengths of photons emitted when electrons jump between discrete energy levels, "shells" around the atom of a certain chemical element.
The fomula was invented by the Swedish physicist Janne Rydberg and presented on November 5, 1888.

By setting <math>n_1</math> to 1 and letting <math>n_2</math> run from 2 to infinity, the spectral lines known as the Lyman series[?] converging to 91nm are obtained, in the same manner:
<math>n_1</math>  <math>n_2</math>  Name  Converge toward 
1  <math>2 \rightarrow \infty</math>  Lyman series[?]  91nm 
2  <math>3 \rightarrow \infty</math>  Balmer series[?]  365nm 
3  <math>4 \rightarrow \infty</math>  Paschen series[?]  821nm 
Rydberg formula for any element
